VAPORIZER FOR HYDROCARBON-IVIOTORS.

SPECIFICATION forming part of Letters Patent No. 775,321. dated November 22, 1904. Application filed November 24, 1903. Serial No. 182,455. (No modela To {rf/ wit/mt t www concern:

Be it known that I, AUGUST VAssuANN, a citizen of the United States, residing at Halletts Point, Astoria, Queens county, and State of New York, have invented certain new and useful Improvements inVaporizers for Hydrocarbon-Motors, of which the following' is a specification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to motors in which kerosene or other liquid hydrocarbon is used as a source of power, the oil being injected into an ignition-chamber by which it is Vaporized and iiashed.

My improvement relates particularly to the ignition-chamber, and is designed to regulate the temperature of the same to prevent carbonization 0f the hydrocarbon, to prevent deterioration of the metal of which the igniterchamber is formed, to insure the perfect combustion and reduction of all the hydrocarbon, and to prevent serious injury by reason of accidental contact with the exterior of the ignition-chamber.

I have heretofore found by experience that if the igniter attains a very high temperature there is a loss of power by reason of the carbonization of the oil on the interior surface of the igniter or its reduction thereby to a spheroidal state, in either of which conditions it passes out through the discharge-port without performing any work and is lost. As a mattei' of fact, after a motor of this class has been running for awhile and the ignitionchamber has become heated to the maximum degree its surface glows cherry red as seen in the dark, and serious burns have resulted from accidental contact therewith, aside from the loss of power. As illustrating' the latter, I have found that after the preliminary starting of the motor it becomes less effective with the same charge of fuel. Thus at the start a motor will run, say, six hundred revolutions per minute and then fall off to five hundred per minute after running awhile, the ignitionchamber having attained and maintaining an excess of heat over that requisite to vaporize and explode the oil, as before stated. Another serious trouble arising from the overheating of the metal of which the igniter is formed is that the metal deteriorates rapidly and under certain conditions is liable to suddenfractnre, as by reason of contact with cold water or from unexpected and abrupt reduction in temperature, or the metal may become so weakened as to be unable to resist the internal pressure resulting from the explosion of a charge or the ex terior pressure resulting from the succeeding vacu um created in the engine, in which case either an explosion or collapse of the chamber occurs.

1 overcome these objectionable features and insure a maximum of speed with a minimum of fuel by means of my invention, which consists, essentially, in regulating the temperature of the ignition-chamber bymeans of a water circulation controlled by certain valves arranged to be used in conjunction with a water jacket or hood on thc top vof the ignition-cham ber, substantiall. Y as hereinafter described and claimed specifically.

The accompanying drawing represents diagramatically a sectional elevation of the parts of a kerosene-oil motor essential to an understanding of my invention.

S is the piston-cylinder, formed with the usual lwater-jacket s, having the inlet-pipe and valve i and the outlet n and valve n.

C is the ignition-chamber, formed with thc hood c, having' the water-space c' surrounding the upper portion of the igniter-chamber to a greater or less extent, as may be found most expedient.

c2 is the channel or inlet in which the end of the fluid-feed injector isinserted. This inlet c2 is formed with a water-jacket e, communicating through the passage c" with the waterjacket of the cylinder S.

u is an auxiliary pipe or conduit by which communication is established between the water-space c in the hood c and indirectly through the jacket c with the water-space s of the cylinder S, a valve a' being interposed in said pipe a` for the purpose of regulating and controlling the fiow offluid to the hood c.

(Z is a discharge-pipe connecting the waterspace c with the main discharge-pipe D by means of the T-joint CZ', which also communicates with the outlet o and valve 0'.

It is obvious that by closing the valve o more or less and opening the valve a more or less to correspond any desired amount of the water entering the water-space under pressure from the inlet-pipe c' may be shunted or deected through the water-spaces 03 c and that the temperature ofthe ignition-chamber may thus be controlled with accuracy, so that the disadvantages hereinbefore enumerated may be avoided.

It is obvious that the valve o' may alone be relied upon to control the forced circulation of water through the igniter, since by shutting it olf entirely the water in the jacket s passes in the injector, so that I do not limit myself to the use of the valve a.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In amotor of the character designated, the combination of a piston-cylinder formed with a water-jacket, means for introducing water into said jacket, an ignition-chamber communicating with said piston-cylinder and formed with a hood having a water-space therein, means for admitting water from the said cylinder water-jacket to the said hood on the igniter, means for controlling the flow of water to said hood and means for discharging water from said hood for the purpose described.

2. In a motor of the character designated, the combination of a piston-cylinder formed with a water-jacket, means for introducing water into said jacket, means interposed between the main discharge-pipe and said waterjacket for controlling the direct discharge of Water therefrom, an ignition-chamber communicating with said piston-cylinder and formed with a hood having a Water-space therein, means for admitting water from the said cylinder water-jacket to the said igniter-hood, means for controlling the ilow of water to said hood and means for discharging water from said hood, for the purpose described.

3. In a motor of the character designated the combination of a piston-cylinder formed with a water-jacket, means for introducing water into said water-jacket, an ignition-chamber' communicating with said piston-cylinder, said ignition-chamber being formed with a waterjacket around the feed-injector inlet which feed-inlet water-jacket is in communication with ,the water-jacket of the piston-cylinder, said ignition-chamber being also formed with a hood having a water-space, means for conducting Water from said feed-inlet waterjacket to the water-space in said hood and means for discharging the water from said hood, for the purpose described.

4. In a motor of the character designated, the combination of a piston-cylinder formed with a water-jacket, means for introducing water into said water-jacket an igniter-chamber communicating with said piston-cylinder, said ignition-chamber being formed with a waterjacket around the fluid-injector inlet which feed-inlet water-jacket is in communication with the water-jacket in the piston-cylinder, said ignition-chamber being also formed with a hood having a water-space, means for conducting water from said feed-inlet waterjacket to the water-space in the said hood, means for controlling the flow of water to said hood, and means for discharging water therefrom for the purpose described.

5. In a motor of the character designated, the combination of a piston-cylinder formed with a water-jacket, means for introducing water into said jacket, means interposed between the main discharge-pi pe and said water-jacket forcontrolling the direct discharge of water therefrom, an ignition-chamber communicating with said piston-cylinder, said ignitionchamber being formed with'a water-jacket around the feed-injector inlet which feed-injector-inlet water-jacket is in communication with the water-jacket of the piston-cylinder, said ignition-chamber being also formed with a hood having a water-space, means for conducting water from said feed -inlet waterjacket to the water-space in said hood and means for discharging the water from said hood, for the purpose described.

6.
